2025-02-08libgcc: On FreeBSD use GCC's crt objects for static linkingDimitry Andric1-1/+1
Add crtbeginT.o to extra_parts on FreeBSD. This ensures we use GCC's crt objects for static linking. Otherwise it could mix crtbeginT.o from the base system with libgcc's crtend.o, possibly leading to segfaults. libgcc: PR target/118685 * config.host (*-*-freebsd*): Add crtbeginT.o to extra_parts.

2025-01-28arm: libgcc: make -spec=sync-*.specs compatible with LTO [PR118642]Richard Earnshaw3-3/+3
The arm-none-eabi port provides some alternative implementations of __sync_synchronize for different implementations of the architecture. These can be selected using one of -specs=sync-{none,dmb,cp15dmb}.specs. These specs fragments fail, however, when LTO is used because they unconditionally add a --defsym=__sync_synchronize=<implementation> to the linker arguments and that fails if libgcc is not added to the list of libraries. Fix this by only adding the defsym if libgcc will be passed to the linker. libgcc/ PR target/118642 * config/arm/sync-none.specs (link): Only add the defsym if libgcc will be used. * config/arm/sync-dmb.specs: Likewise. * config/arm/sync-cp15dmb.specs: Likewise.

2025-01-07[PATCH] libgcc/m68k: More fixes for soft floatKeith Packard2-48/+47
Fix __extenddfxf2: * Remove bogus denorm handling block which would never execute -- the converted exp value is always positive as EXCESSX > EXCESSD. * Compute the whole significand in dl instead of doing part of it in ldl. * Mask off exponent from dl.l.upper so the denorm shift test works. * Insert the hidden one bit into dl.l.upper as needed. Fix __truncxfdf2 denorm handling. All that is required is to shift the significand right by the correct amount; it already has all of the necessary bits set including the explicit one. Compute the shift amount, then perform the wide shift across both elements of the significand. Fix __fixxfsi: * The value was off by a factor of two as the significand contains 32 bits, not 31 so we need to shift by one more than the equivalent code in __fixdfsi. * Simplify the code having realized that the lower 32 bits of the significand can never appear in the results. Return positive qNaN instead of negative. For floats, qNaN is 0x7fff_ffff. For doubles, qNaN is 0x7fff_ffff_ffff_ffff. Return correctly signed zero on float and double divide underflow. This means that Ld$underflow now expects d7 to contain the sign bit, just like the other return paths. libgcc/ * config/m68k/fpgnulib.c (extenddfxf2): Simplify code by removing code that should never execute. Fix denorm shift test and insert hidden bit as needed. (__truncxfdf2): Properly compue and shift the significant right. * config/m68k/lb1sf68.S (__fixxfsi): Correct shift counts and simplify.

This patch adds __flashx as a new named address space that allocates objects in .progmemx.data.

2024-11-30openmp: Add crtoffloadtableS.o and use it [PR117851]Jakub Jelinek3-2/+7
Unlike crtoffload{begin,end}.o which just define some symbols at the start/end of the various .gnu.offload* sections, crtoffloadtable.o contains const void *const __OFFLOAD_TABLE__[] __attribute__ ((__visibility__ ("hidden"))) = { &__offload_func_table, &__offload_funcs_end, &__offload_var_table, &__offload_vars_end, &__offload_ind_func_table, &__offload_ind_funcs_end, }; The problem is that linking this into PIEs or shared libraries doesn't work when it is compiled without -fpic/-fpie - __OFFLOAD_TABLE__ for non-PIC code is put into .rodata section, but it really needs relocations, so for PIC it should go into .data.rel.ro/.data.rel.ro.local. As I think we don't want .data.rel.ro section in non-PIE binaries, this patch follows the path of e.g. crtbegin.o vs. crtbeginS.o and adds crtoffloadtableS.o next to crtoffloadtable.o, where crtoffloadtableS.o is compiled with -fpic. 2024-11-30 Jakub Jelinek <jakub@redhat.com> PR libgomp/117851 gcc/ * lto-wrapper.cc (find_crtoffloadtable): Add PIE_OR_SHARED argument, search for crtoffloadtableS.o rather than crtoffloadtable.o if true.

Including the "arm_acle.h" header in aarch64-unwind.h requires stdint.h to be present and it may not be available during the first stage of cross-compilation of GCC. When cross-building GCC for the aarch64-none-linux-gnu target (on any supporting host) using the 3-stage bootstrap build process when we build native compiler from source, libgcc fails to compile due to missing header that has not been installed yet.

2024-10-25non-gcc: Remove trailing whitespaceJakub Jelinek158-1698/+1698
I've tried to build stage3 with -Wleading-whitespace=blanks -Wtrailing-whitespace=blank -Wno-error=leading-whitespace=blanks -Wno-error=trailing-whitespace=blank added to STRICT_WARN and that expectably resulted in about 2744 unique trailing whitespace warnings and 124837 leading whitespace warnings when excluding *.md files (which obviously is in big part a generator issue). Others from that are generator related, I think those need to be solved later. The following patch just fixes up the easy case (trailing whitespace), which could be easily automated: for i in `find . -name \*.h -o -name \*.cc -o -name \*.c | xargs grep -l '[ ]$' | grep -v testsuite/`; do sed -i -e 's/[ ]*$//' $i; done I've excluded files which I knew are obviously generated or go FE.

2024-10-24Use unique_ptr in more places in pretty_printer/diagnostics [PR116613]David Malcolm1-0/+1
My forthcoming patches for PR other/116613 make much more use of cloning of pretty_printers than before, so it makes sense as a preliminary patch for the result of pretty_printer::clone to be a std::unique_ptr, rather than add more manual uses of "delete". On doing so, I noticed various other places where naked new/delete is used for run-time configuration of diagnostics: * the output format (text vs SARIF) * client data hooks * the option manager * the URLifier Hence this patch also makes use of std::unique_ptr and ::make_unique for managing such client policy classes, and also for diagnostic_buffer's per-format implementations. Unfortunately we can't directly include <memory> in our internal headers but instead any of our TUs that make use of std::unique_ptr must #define INCLUDE_MEMORY before including system.h. Hence the bulk of this patch is taken up with adding a define of INCLUDE_MEMORY to hundreds of source files: everything that includes diagnostic.h or pretty-print.h (and thus anything transitively such as includers of lto-wrapper.h, c-tree.h, cp-tree.h and rtl-ssa.h).

2024-10-14RISC-V: Add detailed comments on processing implied extensions. [NFC]Yangyu Chen1-3/+6
In some cases, we don't need to handle implied extensions. Add detailed comments to help developers understand what implied ISAs should be considered. libgcc/ChangeLog: * config/riscv/feature_bits.c (__init_riscv_features_bits_linux): Add detailed comments on processing implied extensions. Signed-off-by: Yangyu Chen <chenyangyu@isrc.iscas.ac.cn>
2024-10-14RISC-V: Implement __init_riscv_feature_bits, __riscv_feature_bits, and ↵Kito Cheng2-0/+410
__riscv_vendor_feature_bits This provides a common abstraction layer to probe the available extensions at run-time. These functions can be used to implement function multi-versioning or to detect available extensions. The advantages of providing this abstraction layer are: - Easy to port to other new platforms. - Easier to maintain in GCC for function multi-versioning. - For example, maintaining platform-dependent code in C code/libgcc is much easier than maintaining it in GCC by creating GIMPLEs... This API is intended to provide the capability to query minimal common available extensions on the system. The API is defined in the riscv-c-api-doc: https://github.com/riscv-non-isa/riscv-c-api-doc/blob/main/src/c-api.adoc Proposal to use unsigned long long for marchid and mimpid: https://github.com/riscv-non-isa/riscv-c-api-doc/pull/91 Full function multi-versioning implementation will come later. We are posting this first because we intend to backport it to the GCC 14 branch to unblock LLVM 19 to use this with GCC 14.2, rather than waiting for GCC 15. Changes since v7: - Remove vendorID field in __riscv_vendor_feature_bits. - Fix C implies Zcf only for RV32. - Add more comments to kernel versions. Changes since v6: - Implement __riscv_cpu_model. - Set new sub extension bits which implied from previous extensions. Changes since v5: - Minor fixes on indentation. Changes since v4: - Bump to newest riscv-c-api-doc with some new extensions like Zve*, Zc* Zimop, Zcmop, Zawrs. - Rename the return variable name of hwprobe syscall. - Minor fixes on indentation. Changes since v3: - Fix non-linux build. - Let __init_riscv_feature_bits become constructor Changes since v2: - Prevent it initialize more than once. Changes since v1: - Fix the format. - Prevented race conditions by introducing a local variable to avoid load/store operations during the computation of the feature bit.
